I have a problem with FPS and lags/stutter. I spent hours looking through forums and trying different things but it keeps behaving wierd.
I will mention in advance that:
- I use laptop (Intel i9-10980HK, GeForce RTX 3080, 32GB RAM) with external monitor (LG 27gl850)
- I have only dedicated graphic card (no need to turn off integrated one)
- I have my game on C:/Games
- I have disabled game bar
- I set High performance in Graphics
- I installed DirectX9
- I tried changing API to "opengl" but it just makes it worse.
- I did everything mentioned here by Torta and others: viewtopic.php?t=5329
- I tried disabling all addons
On top of that i of course installed VanillaFixes.
I tried using VanillaFixes with dxvk, without it and installing manually (plus uncommented borderless support in dxvk.conf i also played with FPS CAP). After that my FPS went up from ~60 FPS to 144 FPS and game started running smoothly. BUT here comes the wierd part - after some time running around and killing mobs my FPS drops to ~40-60 and it becomes laggy and uplayable. I don't know why it is good for around 5-10 minutes and then it breaks.
After that i installed VanillaTweaks.
When i simply tweak WoW.exe with all default settings it completly breaks the game, ~30FPS, lags, stutter etc. When i played with the settings and turned off frilldistance, farclip, fov, nameplatedistance it seems to be ok. I reach 144FPS but again after 5-10 minutes running around and killing mobs it breaks again and goes down to ~40-60FPS and becomes laggy etc. Below is my vanilla-tweaks command.

Another wierd thing is that sometimes when i run TWoW i start "broken" with ~40-60FPS and laggy. I need to close it and re run (cometimes couple of times) so i start with stable 144FPS but as i mentioned before it breaks again after some time.
Tried with clean client
I tried downloading clean client since i was doing alot of changes. On clean client my FPS jump from 60 to 100 with minor random lags and stutters (i suppouse it's normal for everyone). However the wierd things that games starts "broken" with low fps and stays there remains even on clean client. I sometimes have to rerun the game to have it fixed.
Any suggestions what i can do more?
Thanks for help in advance!
